Data Flow Script: field name causing error

Question

My Source is the following JSON:

{
  "stores": "test"
}

My Data Flow Script is the following:

source(output(
        stores as string
    ),
    allowSchemaDrift: true,
    validateSchema: false,
    ignoreNoFilesFound: false,
    documentForm: 'singleDocument') ~> source1

When I run the data preview, I get the following error:

Error:
DF-DSL-001 DSL stream has parsing errors
Line 2 Position 2: no viable alternative at input 'output(\n\t\tstores' - RunId: 2f5e92eb-1d00-4b1e-ab1e-d56822f3d8aa

If I change the JSON field name to "store", and modify the data flow script accordingly, there is no issue.

I assume stores is a reserved word? I have tried escaping with backticks or single/double quotes but these are not accepted as valid scripts.

Answer 1

Try this: {stores}

Sounds like a possible bug. Would you mind filing a support ticket from the Azure portal?
